Description

Technical Field

[0001] The utility model relates to the technical field of winding devices, in particular to a guide needle angle adjustment mechanism. Background Art

[0002] Coil usually refers to a ring-shaped wire winding. The most common coil applications include: motors, inductors, transformers and ring antennas. Generally, the wires are wound one by one, and the wires are insulated from each other. Stator winding refers to the winding installed on the stator. It is ring-shaped and has multiple winding posts at intervals on the inner wall. The three-axis moving device drives the guide needle to extend into the interior to wind the wire on the winding post. After completing the winding of one winding post, it moves to another winding post for winding, and the winding is realized in this cycle. The winding mechanism in the prior art is a needle holder device of a VCM motor coil winding machine disclosed in patent number CN201820501343.X. The needle holder device of the VCM motor coil winding machine includes a main beam and a needle seat and a cutter installed on the main beam. The square needle seat is installed in the square hole of the main beam. The needle seat can be adjusted forward and backward, but cannot be rotated axially. After adjusting the forward and backward positions, the needle seat can be locked with a first screw. A round hole is provided on the needle seat, and the guide needle passes through the round hole. After adjusting the upper and lower positions of the guide needle, the guide needle can be locked with a second screw. However, it is difficult for the guide needle mechanism in the prior art to adjust the angle of the guide needle. When some coils are wound, it is necessary to cross the wire on the outside of the coil skeleton, that is, after completing the winding of one winding post, the wire needs to be connected to another winding post on the outer wall of the coil skeleton. When the guide needle is always kept in a vertical state, it is difficult to achieve outside cross-wire and some special winding methods. Utility Model Content

[0014] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0015] like Figure 1 to Figure 2As shown, it is a schematic diagram of the structure of the guide needle angle adjustment mechanism provided by the utility model. The guide needle angle adjustment mechanism includes a base plate 10, a sliding component 20 arranged on the base plate 10, a driving component 30 arranged on the sliding component 20, and at least one guide needle component 40 arranged on the base plate 10. It can be imagined that the guide needle angle adjustment mechanism also includes some other functional modules, such as a connecting component, a sensor, and a mounting component, etc., which are well known to those skilled in the art and will not be repeated here.

[0016] The substrate 10 is used to carry the above-mentioned components. At the same time, the substrate 10 is arranged on the three-axis moving device of the winding machine, thereby driving the guide needle angle adjustment mechanism to move three axes for winding. It should be the existing technology and will not be repeated here.

[0017] The sliding assembly 20 includes two slide rails 21 disposed on the base plate 10, a slide plate 22 disposed on the slide rails 21, and at least one clamping block 23 disposed on the slide plate 22. The extension direction of the slide rails 21 is parallel to the direction of gravity so that the slide plate 22 can move vertically. The clamping block 23 is used to set the guide needle assembly 40.

[0018] The driving component 30 is used to drive the sliding component 20 to move linearly. The driving component 30 in this embodiment is a screw device. The screw device can obtain a larger thrust with a relatively small torque, and the transmission efficiency is higher. The driving component 30 should be a prior art and will not be described in detail.

[0019] The guide needle assembly 40 includes a bracket 41 arranged on the substrate 10, a rotating member 42 arranged on the bracket 41, a connecting rod 43 connecting the sliding assembly 20 and the rotating member 42, a wire passing porcelain eye 44 arranged on the bracket 41, a plurality of wire passing wheels 45 arranged on the bracket 41 and the rotating member 42, and a guide needle 46 arranged on the rotating member 42.

[0020] The bracket 41 is provided with a through hole 411, and the through hole 411 is used to pass the connecting rod 43 and provide a swinging space for the connecting rod 43. The bottom of the bracket 41 is provided with an extension section 412, one end of which is connected to the bracket 41, and the other end has two spaced extension fingers 413. The extension direction of the extension section 411 is parallel to the central axis of the through hole 411. The two extension fingers 413 are used to rotate the rotating member 42 in the middle.

[0021] The middle position of the rotating member 42 is rotatably connected to the extending finger 413. The guide needle 46 is arranged at one end of the rotating member 42, and the other end is rotatably connected to one end of the connecting rod 43, so that the rotating member 42 is driven by the connecting rod 43 to adjust the angle of the guide needle. The rotating member 42 is hollow, and a guide wheel for guiding the guide wire is arranged inside the hollow.

[0022] One end of the connecting rod 43 is rotatably connected to the clamping block 23 of the sliding assembly 20, and the other end is rotatably connected to the rotating member 42. The wire eyelet 44 is located at one end of the bracket 41 close to the sliding assembly 20. The plurality of wire wheels 44 are respectively located between the two extending fingers 413 and the rotating member 42. The wire is pulled from the external storage tube and passes through the wire eyelet 44, then moves along the extension section 411 and bypasses the wire wheel between the two extending fingers 413 and the wire wheel on the rotating member 42, and finally passes through the guide needle 46.

[0023] When the driving assembly 30 drives the sliding assembly 20 to move vertically, it can drive the connecting rod 43 to move vertically, so that the connecting rod 43 drives one end of the rotating member 42 to move, so that the rotating member 42 rotates around the center, thereby adjusting the angle of the guide pin 46 at the other end.

[0024] Compared with the prior art, the guide needle angle adjustment mechanism provided by the utility model is configured to rotatably connect the middle position of the rotating member 42 with the extended finger 413, and the guide needle 46 is arranged at one end of the rotating member 42, and the other end is rotatably connected with one end of the connecting rod 43, so that the rotating member 42 and the guide needle 46 are driven to rotate through the multi-stage rotation connection to adjust the angle of the guide needle 46. At the same time, since the rotating member 42 and the connecting rod 43 are connected in multiple stages, only the rotating member 42 rotates, so the space required for rotation is smaller, and the guide needle 46 can be inserted into a coil skeleton with a smaller diameter, thereby improving applicability.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
